MongoDB\Driver\BulkWriteCommand::__construct — Create a new BulkWriteCommand

### Beschreibung

public MongoDB\Driver\BulkWriteCommand::__construct(?array `$options` = `null`)

Constructs a new MongoDB\Driver\BulkWriteCommand, which may be used to perform many insert, update, and delete operations on multiple collections in a single request using the » bulkWrite command introduced in MongoDB 8.0. This differs from MongoDB\Driver\BulkWrite, which is supported by all server versions but limited to a single collection.

After all write operations have been added, this object may be executed with MongoDB\Driver\Manager::executeBulkWriteCommand().

### Parameter-Liste

`options` (array)

  options
  Option | Type | Description | Default
  --- | --- | --- | ---
  bypassDocumentValidation | bool | If `true`, allows insert and update operations to circumvent document level validation. | `false`
  comment | mixed | An arbitrary comment to help trace the operation through the database profiler, currentOp output, and logs.
  let | array|object | Die Zuordnung von Parameternamen und -werten. Die Werte müssen Konstanten oder geschlossene Ausdrücke sein, die nicht auf Dokumentfelder verweisen. Auf die Parameter kann dann als Variablen im Kontext eines aggregierten Ausdrucks zugegriffen werden (z. B. `$$var`). Diese Option ist ab MongoDB 5.0 verfügbar. Wenn sie für eine ältere Serverversion angegeben wird, kommt es bei der Ausführung zu einer Exception.
  ordered | bool | Whether the operations in this bulk write should be executed in the order in which they were specified. If `false`, writes will continue to be executed if an individual write fails. If `true`, writes will stop executing if an individual write fails. | `true`
  verboseResults | bool | Whether detailed results for each successful operation should be included in the returned MongoDB\Driver\BulkWriteCommandResult. | `false`

### Fehler/Exceptions

- Wirft eine MongoDB\Driver\Exception\InvalidArgumentException, wenn beim Analysieren von Argumenten ein Fehler auftritt.

### Beispiele

Beispiel #1 MongoDB\Driver\BulkWriteCommand::__construct() example

`<?php
$manager = new MongoDB\Driver\Manager;
$bulk = new MongoDB\Driver\BulkWriteCommand;
// Delete documents from both collections
$bulk->deleteMany('db.coll_one', []);
$bulk->deleteMany('db.coll_two', []);
// Insert documents into two collections
$bulk->insertOne('db.coll_one', ['_id' => 1]);
$bulk->insertOne('db.coll_two', ['_id' => 2]);
$bulk->insertOne('db.coll_two', ['_id' => 3]);
// Update a document in "coll_one"
$bulk->updateOne('db.coll_one', ['_id' => 1], ['$set' => ['x' => 1]]);
$result = $manager->executeBulkWriteCommand($bulk);
printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Updated %d document(s)\n", $result->getModifiedCount());
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    Inserted 3 document(s)
    Updated  1 document(s)
